Use the Check Syntax button to verify your work. Any syntax or spelling errors will be reported by line and character position.

Answer: TABLESAMPLE SYSTEM (1000 ROWS)

Explanation:

Update line 3 to get the following: SELECT *

FROM Customers

TABLESAMPLE SYSTEM (1000 ROWS)

The TABLESAMPLE clause limits the number of rows returned from a table in the FROM

clause to a sample number orPERCENT of rows.

Syntax: TABLESAMPLE [SYSTEM] (sample_number [ PERCENT | ROWS ] ) References: https://technet.microsoft.com/en-us/library/ms189108(v=sql.105).aspx

Question No: 124

You plan to write a query for a new business report that will contain several nested queries.

You need to ensure that a nested query can call a table-valued function for each row in the main query.

Which query operator should you use in the nested query?

  1. CROSS APPLY

  2. INNER JOIN

  3. OUTER JOIN

  4. PIVOT

Answer: A Explanation:

The APPLY operator allows you to invoke a table-valued function for each row returned by an outer table expression of a query. The table-valued function acts as the right input and the outer table expression acts as the left input. The right input is evaluated for each row from the left input and the rows produced are combined for the final output. The list of columns produced by the APPLY operator is the set of columns in the left input followed by the list of columns returned by the right input.

There are two forms of APPLY: CROSS APPLY and OUTER APPLY. CROSSAPPLY returns only rows from the outer table that produce a result set from the table-valued function. OUTER APPLY returns both rows that produce a result set, and rows that do not, with NULL values in the columns produced by the table-valued function.

Global customers place orders from several countries.

You need to view the country from which each customer has placed the most orders. Which Transact-SQL query do you use?

  1. SELECT CustomerID, CustomerName, ShippingCountry FROM

    (SELECT c.CustomerID, c.CustomerName, o.ShippingCountry, RANK() OVER (PARTITION BY c.CustomerID

    ORDER BY COUNT(o.OrderAmount) ASC) AS Rnk FROM Customer c

    INNER JOIN Orders o

    ON c.CustomerID = o.CustomerID

    GROUP BY c.CustomerID, c.CustomerName,

  2. ShippingCountry) cs WHERE Rnk = 1

  3. SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM Customer c

    INNER JOIN

    (SELECT CustomerID, ShippingCountry, COUNT(OrderAmount) AS OrderAmount FROM Orders

    GROUP BY CustomerID, ShippingCountry) AS o ON c.CustomerID = o.CustomerID

    ORDER BY OrderAmount DESC

  4. SELECT CustomerID, CustomerName, ShippingCountry FROM

    (SELECT c.CustomerID, c.CustomerName,

  5. ShippingCountry,

    RANK() OVER (PARTITION BY c. CustomerID

    ORDER BY o. OrderAmount DESC) AS Rnk FROM Customer c

    INNER JOIN Orders o

    ON c.CustomerID = o.CustomerID

    GROUP BY c.CustomerID, c.CustomerName,

  6. ShippingCountry) cs WHERE Rnk = 1

  7. SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM Customer c

INNER JOIN

(SELECT CustomerID, ShippingCountry, RANK() OVER (PARTITION BY CustomerID

ORDER BY COUNT(OrderAmount) DESC) AS Rnk FROM Orders

GROUP BY CustomerID, ShippingCountry) AS o ON c.CustomerID = o.CustomerID

Where o.Rnk = 1

Answer: C

Question No: 126

Your application contains a stored procedure for each country. Each stored procedure accepts an employee identification number through the @EmpID parameter.

You need to build a single process for each employee that will execute the appropriate stored procedure based on the country of residence.

Which approach should you use?

  1. A SELECT statement that includes CASE

  2. Cursor

  3. BULK INSERT

  4. View

  5. A user-defined function

Answer: E Explanation:

SQL Server user-defined functions are routines that accept parameters, perform an action, such as a complex calculation, and return the result of that action as a value. The return value can either be a single scalar value or a result set.

Question No: 127

You use a Microsoft SQL Server 2012 database that contains two tables named SalesOrderHeader and SalesOrderDetail. The indexes on the tables are as shown in the exhibit. (Click the Exhibit button.)

image

You write the following Transact-SQL query:

image

You discover that the performance of the query is slow. Analysis of the query plan shows table scans where the estimated rows do not match the actual rows for SalesOrderHeader by using an unexpected index on SalesOrderDetail.

You need to improve the performance of the query. What should you do?

  1. Use a FORCESCAN hint in the query.

  2. Add a clustered index on SalesOrderId in SalesOrderHeader.

  3. Use a FORCESEEK hint in the query.

  4. Update statistics on SalesOrderId on both tables.

Note:

  • First function header

  • Then declare that the function returns a datetime

  • Thirdly begin the function body.

  • Fourthly declare the return variable

  • At last include the code that retrieves the required date.

Question No: 129 HOTSPOT

You are developing a SQL Server database for an order management system. The database contains a table that is defined by the following Transact-SQL statement:

image

Transactions must commit if there are no errors. Transactions must roll back if constraint violations occur.

You need to create the Transact-SQL script to insert new orders.

How should you complete the relevant Transact-SQL script? To answer, select the appropriate Transact-SQL statements from each list in the answer area.

image

Answer:

image

Explanation:

image

Box 1: SET XACT_ABORT ON;

XACT_ABORT specifies whether SQL Server automatically rolls back the current

transaction when a Transact-SQL statement raises a run-time error.

When SET XACT_ABORT is ON, if a Transact-SQL statement raises arun-time error, the entire transaction is terminated and rolled back.

Box 2: IF (XACT_STATE()) =-1

If XACT_STATE has the value of -1, then the current request has an active user transaction, but an error has occurred that has caused the transaction to beclassified as an uncommittable transaction. The request cannot commit the transaction or roll back to a savepoint; it can only request a full rollback of the transaction.

Box 3: IF (XACT_STATE()) =1

If XACT_STATE has the value of 1, then the current request has an active user transaction. The request can perform any actions, including writing data and committing the transaction.

Question No: 130

You administer a Microsoft SQL Server 2012 database. The database contains a table named Employee.

Part of the Employee table is shown in the exhibit. (Click the Exhibit button.)

image

image

Unless stated above, no columns in the Employee table reference other tables.

Confidential information about the employees is stored in a separate table named EmployeeData. One record exists within EmployeeData for each record in the Employee table.

You need to assign the appropriate constraints and table properties to ensure data integrity and visibility.

On which column in the Employee table should you create a self-reference foreign key constraint?

  1. DateHired

  2. DepartmentID

  3. EmployeeID

  4. EmployeeNum

  5. FirstName

  6. JobTitle

  7. LastName

  8. MiddleName

  9. ReportsToID
